“…The main function of the RFID reader is transmitting the interrogational signal toward the chipless tag, with magnitude and phase data. Subsequently, the interrogation signal is encoded into different frequency spectra according to the magnitude and phase and then retransmitted to the reader by the multiresonator chipless tag [ 7 , 21 , 49 , 57 , 58 ]. Figure 1 shows a block diagram of the introduced chipless RFID system.…”

A novel methodology is proposed to reliably predict the resonant characteristics of a multipatch backscatter-based radio frequency identification (RFID) chipless tag. An ultra-wideband impulsion radio (UWB-IR)-based reader interrogates the chipless tag with a UWB pulse, and analyzes the obtained backscatter in the time domain. The RFID system consists of a radar cross-section (RCS)-based chipless tag containing a square microstrip patch antenna array in which the chipless tag is interrogated with a UWB pulse by an UWB-IR-based reader. The main components of the backscattered signal, the structural mode, and the antenna mode were identified and their spectral quality was evaluated. The study revealed that the antenna-mode backscatter includes signal carrying information, while the structural mode backscatter does not include any tag information. The simulation findings were confirmed by experimental measurements obtained in an anechoic chamber environment using a 6-bit multipatch chipless RFID tag. Finally, the novel technique does not use calibration tags and can freely orient tags with respect to the reader.

“…Next, the uncalibrated signals (i.e., without background normalization) based techniques are discussed. A time and frequency domains (TD-FD) analysis [31] and a scalar method [32] are presented without attaching the tag on objects and without considering aspect angles. Two works in the literature [33], [34] are based on the short-time Fourier transform (STFT).…”

This paper presents the extraction of aspectindependent parameters for dual-L dipoles based chipless radio frequency (RF) identification (RFID) tags using spectrogram method using single measurement. The implemented spectrogram method is based on a single short-time Fourier transform (STFT) averaging window. The performance of the spectrogram method is compared to the matrix pencil method (MPM). A computational time comparison between the spectrogram method and MPM is presented.Index Terms-Chipless radio frequency (RF) identification (RFID), matrix pencil method (MPM), quality factor, short time Fourier transform (STFT).
